Abstract
A temperature-compensated output buffer is disclosed that incorporates a temperature-compensating network into a GaAs output buffer that has been interfaced to Silicon-based circuitry to regulate the output voltage of the buffer under changing temperature conditions. The temperature-compensating network includes a differential amplifier whose output varies with temperature due to a network of series-connected Schottky diodes. The output of the differential amplifier controls a bleeder MESFET that controls the output voltage of the buffer so that temperature variations do not adversely affect the buffer output.
